Cut out of any openings before installing the InSoFast panels or inserts. There are many methods for installing windows and doors. We will be showing one method for utilizing a wood jamb when a structural header is not required. Whatever method you choose to use, the jambs or framing for any openings should be done before the InSoFast panels are installed.
On a 2×4, trace the corrugation and cut apart. This creates the interior and exterior part of the bottom and top jamb. The side jambs are created in a similar manner, cutting lengthwise with a circular saw set to the angle of the container to accommodate the corrugation.
An additional bead of PL Premium 3x is required around all openings to provide additional bonding around the cuts.
Leave a ¼” gap around all window/door openings to that after all the panels are installed, the gap can be filled with spray foam.
